EO Detective 11-14

These resources link to elements of the geography, while supporting aspects of science, maths and computing. Using early astronaut photographs, and more recent satellite images, they provide opportunities to discuss the advantages and disadvantages of using each method for remote sensing. The main activity is based around using a freely available GIS (Google Earth) and satellite data to explore changes in forest cover in a region in Africa and another in Asia, including reasons for contrasting results and the limitations of the method used. Students are encouraged to think about how Earth Observation scientists decide which data from the extensive sets available might be useful for a particular investigation and how they obtain new images.

They have been produced by the National Centre for Earth Observation.

Resources

Astronaut or Satellite?

This activity introduces the idea of remote sensing and some of the difficulties of obtaining images from orbit by asking students to match photographs taken from the ground with early astronaut photographs.

Exploring Rainforests

In this activity, students examine changes to forests in cross-border regions of Africa and Borneo using Google Earth Pro to help identify features shown in satellite images and make measurements. The context allows students to explore the factors which put pressure on forested areas, and what is being done to protect...

Watching a Glacier (11-14)

This brief activity uses false-colour images of the Columbia glacier to introduce the idea of using sequences of satellite images to monitor change and focuses on the selection of appropriate data for an investigation.

Where Would You Photograph? (11-14)

In this activity students take on the role of Earth observation scientists submitting a request for an image they would like for their research. This gives them the opportunity to consider the possibilities of pictures taken from orbit (and the limitations) and to write scientifically for a specific audience. It can...
